To ALL WIIOM IT MAY eoNcEEN: p l

i Be it known that I, SAMUEL M. WILLIAMS, of' Pine Village, inthe county of Warren, and State of Indiana,

have invented a new and useful Improvement in Evaporator; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a top or plan view of my improved evaporator. I

Figure 2 is a vertical longitudinal section of the same, taken through the line :v 2:, iig. 1.

Figure 3 is a vertical longitudinal section of the same, taken through the line y g/jigl 1.

Figure 4 is a vertical cross-section of the same, taken through the line e a, tig. 1.

Similar letters of reference indicate like parts. I

My invention has for its object tofurnish 'an improved evaporator so constructed and arranged that the tire may be directed under either of the pans at pleasure, or vmay be shut o" from either or-all the pans, as may be' desired; and it consists, first, in an improved evaporator formed by the combination of the `pans with the furnace,- when said furnace is constructed and arranged, asl hereinafter 'more fully described; and, second, in the skimmer formed by the combination of the perforatedplate, handle, and sliding-rod with each other, as hereinafter 4'more fully described.

The furnace A consists of two rectangular boxes placed side by side and securely attached to each other, or of a single large box divided into two parts by a vertical longitudinall partition. The boxes are divided into two ues bythe horizontal partitions al and a2, the vpartition al extending from the [ire-chamber i3 to the rear end ofthe' furnace, and the partition a2 exten-ding the whole length of the furnace. a4 isa damper pivoted to the sides of the furnace at the forward edge of the partition al. -When the damper a4 is turned into the position shown in fig. 1, it closes the lower flue, and compels all .the heat to pass through vthe upper one, and when it is turned up all the heat passes through the lower ue. In the rear part of 'thelfurnace an opening is cut through the interior side walls, and through the partitions att and a2, as shown in figs. 2 and 4.. This opening into therupper flue is closed on each side of the .interior side wallsvof the furnace by the dampers a5. and a6. The opening from the lower flue into the chimney B is closed by a damper, a7, and the opening from the upper Hue into ,the chimney B is closed by a damper, a8. The pivoting-rods of all theseldanpers extend out through.

the s ide walls of the fu'rnace and terminate in handles, so that the dampers'may `be readily,operated.- By means of thes'e dampers the heat may be made to pass all the way from the fire-chamber to the 'chimney through the upper flue or through the lower ue, or part of the way through each, as may be desiredris' the pari.'

'into which the juice is rst put, and in which it is kept till about one-third done. -VThe pan C rests .upon the p side walls of the furnace.' Its bottom forms the top of the upper' flue, and it extends from the chimney to the rear end'of the furnace. The sirup, when about one-third boiled down, is drawn oiffrom the pan C into the pau D through the pipe c1.V For convenience in doing this the pan D should be set 1t-a little lowerlevel than the pan C, as shown in Iig. 4e.` Thepan D rests upon the sidewalls of the furnace, and it is about two-thirds the size of the pan C. When the sirup is about two'thirds boiled down, it is drawn oif through the pipedl and put' into the finishing-pan E. The finishing-pan E rests upon the side walls' of the furnace directly over -the tire chamber,' and it is divided into two parts by the horizontal partition el. The lower part e2 is kept partially lled with water, and the upper part e3 contains the siruptobe 'boiled down. As the water in the part e2 is vaporized, the steam passes oif through the pipe e coiled in the upper part e3 of the pau.y -The pipe e4 discharges the steam into the chimney B. By this arrangement itis impossible to Scorch or burn the Sirup while being finiished, and when the operation is completed the Sirup is drawmoifthrough the pipe e5. F is the skimmer, the l'ierforatedl or wiregauze plate fl of which is pivoted to the cross-bar f2 ofthe handlef, as shown in gsrl and `3. Tothe forward side of the platefl is pivoted the end of the slidingerodfi, Upon the other end of the rod f* is formed an eye or loop which slides back and forth along the said handle, as the skimmer is operated. The ends of the cross-bar fz are ot such a length that they slide along the upper edges ofthe pans and prevent the .plntefl from descending so deep into the pans as to disturbthe sedimenti By means of this skimmer the scum is drawn to and up the inclined rear end ofthe pan C or D, and allowed to fall into the trough G- or H by which it is carried outof the way.

I claim as new, and desire to 'secure by Letters Patent-- An improved evaporator formed by the combination of pans C, D, and E with the furnce A, when said furnace is constructed and arranged substantially as herein described and for the purposes set forth.

The skimmer Eformed by the combinationof the perforated or wire-gauze nlatef, the handlefs, and the sliding-mdf, substantially as described and for the purpose set forth.
